NOVEL ZINC PHOSPHATE PHASES FORMED WITH CHIRAL D-GLUCOSAMINE MOLECULES

Chiral syntheses and separations of both intermediate and final compou nds are currently extremely important areas of research, especially fo r the chemical, pharmaceutical, agrochemical, and biomedical industrie s. We are investigating the synthesis of new inorganic porous material s for enantiomeric selectivity. We present a study of inorganic zinc p hosphate crystalline phases templated with the chiral molecule d-gluco samine hydrochloride. The crystallization of these phases is highly de pendent on reaction time, temperature, and stoichiometry. Resultant ne w phases include a mesoporous phase and a layered phase. Data indicate s that the walls of the new 32 Angstrom sized mesoporous phase are cry stalline and ordered. Characterization techniques applied include powd er X-ray diffraction, TEM, and P-31 MAS NMR.
